Merging a Data Map with an Extraction Map

Merging a Data Map with an Extraction Map

For a DB2 source, you can merge a data map with an extraction map.
For example, if a source table contains columns in which you store data in a format that is inconsistent with the column datatype, you can create a data map to manipulate that data with PowerExchange expressions. If you store packed data in a CHAR column, you might create a data map to manipulate and prepare that data for loading to a target. You can then merge the data map with an extraction map. The extraction map uses the associated data map to map the change data.
  1. Open the extraction group.
  2. Open the extraction map.
  3. On the
    Extraction Group
     tab in the
    Resource Explorer
    , right-click the extraction map and select
    Amend Capture Registrations
    .
  4. In the
    Extract Definition - Amend Capture Registrations
     dialog box appears, select
    Merge
    .
  5. In the
    Bulk Datamap Name
     box, enter a data map name or select a data map:
    • Click the Browse button to browse to the file.
    • In the
      DB2 Datamaps Selection
       dialog box, specify filter criteria under
      DB2 Map Filter Data
       to restrict the list of data maps. You can include wildcards.
    • Click
      Next
      .
    • In the
      Available Datamaps
       list, select a data map and click
      Finish
      .
  6. Click
    OK
    .
    The extraction map uses the associated data map to map the change data. The merged data map appears in the
    Merged With
     field on the
    Extract Definition
     tab of the
    Resource Inspector
    .
